Considerable experimental evidence suggests that non-pecuniary motives must be addressed when modeling behavior in economic contexts. Recent theories of non-pecuniary motives can be classified as altruism-, equity-, or reciprocity-based. We outline the qualitative differences in prediction these alternative explanations yield in a gift-exchange game. We estimate and compare leading approaches in these categories, using experimental data. We then offer a flexible approach that nests the above three approaches, thereby allowing for nested hypothesis testing and for determining the relative strength of each of the competing theories. In addition, the encompassing approach provides a functional form for utility in different settings without the restrictive nature of the approaches nested within it. Using this flexible form for nested tests, we find that intentional reciprocity, distributive concerns, and altruistic considerations all play a significant role in players' decisions.  相似文献

This study addresses changes in the wage structure in Finland between 1977 and 1995, and provides a simple explanation based on the demand for and supply of skills. The single index model of Card and Lemieux (1996) is augmented by incorporating changes in the supply of skills. The augmented model adequately accounts for the changes in relative wages between groups of different education and experience, but does not capture the changes in the within-group distribution.

Many regions have experienced long-run economic fluctuations generated by the life cycles of their dominant industrial clusters. During the downswings in the 1970s and 1980s, proactive structural policies were typically launched in German regions to combat job losses in their core clusters and to create new jobs in new industries. With respect to the German State of Bremen, this paper provides empirical evidence of: (1) a long-run regional downswing; (2) the potential job effects of proactive regional industrial policy programmes in terms of increasing regional employment, by safeguarding jobs in the regional core industries and creating new jobs in new growth industries; and (3) a time pattern in the job effects, which are related to the different generations of programmes.  相似文献

A two-stage wage setting process whose outcomes are identified in the wage drift, at the local level, and in the tariff wage, at the central level, is analyzed. The impact of insider and outsider factors in each stage of the bargaining process is investigated both theoretically and empirically for Italy. In the light of its extreme policy relevance, particular attention is devoted to the analysis of the interrelationships between the wage drift and the tariff wage. Panel data estimation carried out on a sample of 105 Italian three-digit industries and 41 contract groups, reveals that: (1) Insider factors (productivity, inventories and the insider workers power) are important determinants of the wage drift while outsider factors (aggregate wage and unemployment) have a prominent role in determining the tariff wage. (2) Wage drift and tariff wage are closely interrelated.  相似文献

We integrate insights from family business and organizational ecology into the entrepreneurship field by constructing a theoretical framework that explains how the regional context impacts family and non-family start-ups in differing ways. Regional count data models based on a rich longitudinal dataset reveal that while economic factors such as population size and growth in regions are primarily associated with the number of non-family start-ups, factors related to regional embeddedness, such as pre-existing small family businesses as well as favorable community attitudes toward small businesses, are more strongly associated with the number of family start-ups. Our research provides support for the notion that ‘the regional context’ is an important yet under-theorized area for research on venture creation and family business.  相似文献

An improved bootstrap test of stochastic dominance   总被引:1,自引:0,他引:1  
We propose a new method of testing stochastic dominance that improves on existing tests based on the standard bootstrap or subsampling. The method admits prospects involving infinite as well as finite dimensional unknown parameters, so that the variables are allowed to be residuals from nonparametric and semiparametric models. The proposed bootstrap tests have asymptotic sizes that are less than or equal to the nominal level uniformly over probabilities in the null hypothesis under regularity conditions. This paper also characterizes the set of probabilities so that the asymptotic size is exactly equal to the nominal level uniformly. As our simulation results show, these characteristics of our tests lead to an improved power property in general. The improvement stems from the design of the bootstrap test whose limiting behavior mimics the discontinuity of the original test’s limiting distribution.  相似文献

Globalization is associated with pressures and conflicts over natural resources, with migration, urbanization and development. The analyzes these phenomena focusing the Lower Basin of the Zambezi River in Mozambique where external demand over natural resources have been associated with huge projects on transport infrastructures, coal mining and agroforestry, somehow correlated with recurring conflicts. The approach proposes and uses a regional development model that highlights the impacts of the spatial allocation of property rights on income and migration. Results show the importance of resources ownership in the spatial profile of development and social unrest.  相似文献

This article examines trends in relative wages between high- and medium-skilled workers and between medium- and low-skilled workers in Finland, Germany, Italy, South Korea and the US over the period 1970–2005. It is found that there are large differences in the evolution wage inequality across the countries in our sample, with some countries showing a long-run upward trend in relative wages (such as the US, Germany and Italy) and others showing a long-run downward trend (such as Finland and Korea). The main conclusion from our results is that inequality is not an inevitable by-product of technological change.  相似文献

This study explores the effect of economic policy uncertainty (EPU) in four countries or regions (China, Japan, Europe, and the United States) on the contagion risk of investments in the global stock market. The stock returns of 22 stock markets worldwide are analyzed to determine which region’s EPU exhibits the greatest effect on regional systematic risk in the global stock market and on volatility risk in individual stock markets. First, all of the samples, the markets of different continents and the spillover indices of the developed and emerging markets, are calculated to observe the dynamic correlation among these markets with the aim of quantifying regional systematic risk and further examining the contagion risk effect of EPU. The results indicate the following: EPU in China is the most influential, and its contagion risk spreads to different regional markets, except for Europe; the effect of EPU in the United States is inferior to that in China; EPU in Japan merely influences contagion risk in emerging markets; contagion risk in European markets is not influenced by the four EPU indices; and EPU in Europe is not influenced by contagion risk in the global stock market. However, according to the volatility risk in each market, the EPU in Europe and China respectively influence Asian countries and European countries the most. These results may be attributable to the extremely high trade dependence among these countries because the performance of international enterprises is mainly determined by the economic policies of their trading partners.  相似文献

Analyses of household budget surveys, national accounts dataon functional income distribution, and data on the dispersionof wages, indicate that income inequality in Poland, after fallingover the 1993–96 period, rose significantly from 1997onwards. Farmers and the unemployed were the main losers. Theoverall position of wage-earners improved, although wage inequalityincreased sharply in the second half of the 1990s. Employersand the self-employed fared quite well. This coincided withfiscal policy changes which substantially slowed down progressionin income taxes. Over the 1993–96 period growth was highand balanced. Subsequently, growth slowed down, giving riseto serious fiscal and external deficits.  相似文献
